San Francisco deploying paint that causes urine splash back

Don't pee on the wall in San Francisco!

Urinate on certain walls in San Francisco, and you can expect a bit of splash damage on your legs or pants.


Public Works has painted 10 walls using the custom UV-coated paint that helps repel urine - following a similar move in Hamburg, Germany.

To warn potential violators, signs with the following notice also have been included: "Hold it! This wall is not a public restroom. Please respect San Francisco and seek relief in an appropriate place."

The City of San Francisco spends upwards of $14 million every year to help clean up human waste found on walls and streets.

"You're not supposed to be doing that type of act in the first place, right? Hopefully, we can change the behavior of some of the few that use city streets for inappropriate activity," said Mohammed, Nuru, the director of San Francisco Public Works, in a statement to the media.
